SPECIFICATION forming part of Letters Patent No. 752,240, dated February 16, 1904.

l Application filed February 18, 1903. Serial No. 144,060. (No model.)

To all whom it may concern.-

Be it known that I, JOHN A. MAREK, aicitizen of the United States, residing at Lewiston, in the county of Nez Perces, State of Idaho, have invented certain new and useful Improvements in Fluid-Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use thersame. Y

This invention relates to fluid-motors such as may be operated either by air or water; and it has for its object to provide a simple and eflicient construction wherein thepower-v wheel may be arranged below the surface of the water, while said power-wheel and its cooperating parts may be readily lifted to permit of repairs.

Other objects and advantages of the invention will be understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation showing a motor embodying the present invention. Fig. 2 is a top plan View of the motor withthe top frame removed. Fig. 3 is a central section taken longitudinally through the power-wheel and its casing, Fig. 4 is an end view of the power-wheel.

Referring now to the drawings, the present motor comprises a cylindrical casing 5, at the ends of which are transverse supports 7 and 8, in which are bearings 9 and 10, which are water-tight and in which are received the ends of the power-shaft 11. Upon the powershaft are fixed a number of wheels each including a plurality of blades 12, which radiate from a hub 13, and which blades are turned at angles to the shaft to give the desired pitch. The diameters of the wheels are nearly equal to the internal diameter of the casing in the rear of the flared portions, so that the wheels fit the casing with suflicient snugness toprevent substantial loss of power by the motive fluid passing between the wheels and the eas- FLUID-MOTOR. I I

ing. To prevent drift or other objectionable matter entering the casing, the flared end of the casing isprovided with a screen 14.

Upon the casing 5 are pillow-blocks l5, in which is journaled a driving-shaft 16, provided with sprocket-wheels 17, with which are engaged chains 18. a On the power-shaftaresprocket-wheels 19, corresponding in location to the wheels 17, and which sprockets are engaged by the driving-chains 18. The driving-shaft is provided with a pulley 20, with which may be connected a belt for drive ing whatever machinery may be desired. To conveniently oil the bearings for the power: shaft, cups 21 are mounted upon the pillow: blocks on the casing, and from these cups lead oil-tubes 22 to the bearings.

The casing 5 is disposed in a frame including four vertical uprights 23, which when the machine is used as a water-motor are firmly anchored, and slidably engaged with these uprights are the transverse arms 24, secured to the upper and lower sides, respectively, of the casing, so that the casing may be raised and lowered upon the uprights as guides. tual relation, they. are connected at their upper ends by the cross-beams 25.

When the casing or any of the parts carried thereby is in need of repair, said casing may be raised upon the guides, and to facilitate To hold the uprights in proper mui this raising operation a winding-shaft 26 is provided and is mounted in hangers secured to corresponding cross-beams 25. The winding-shaft 26 has drums 27 thereon, with which are engaged cables 28, having their ends at,- tached to a casing 5, so that when the winding-shaft is rotated the cables will be wound up to raise the casing and the parts carried thereby. To rotate the winding-shaft, ahandwheel 29 is provided, and to hold the windingshaft with the casing raised a pawl 30 is arranged for engagement with a ratchet 31 on the shaft. To give access to the casing 5,

doors 32 are provided at points near to the sprocket-wheels on the power-shaft.

On the casing 5 at any suitable point thereof is mounted a pump 33, which is operated from a chain 34:, connected to a sprocket-wheel on the driving-shaft.

It will be understood that this motor may be sunk in a body of water for the passage of currents therethrough either by natural flow of the body of Water or by waves or that it may be placed to receive water from a dam or may even be elevated, so that wind may blow through it to rotate the wheels and operate any mechanism that may be connected therewith.

To regulate the flow of motive fluid through the casing 5, a two-part gate is provided and includes wings 32' and 33 and which are bent transversely to inclose the end of the casing, with their extremities overlapping, and through these overlapped extremities and the wall of the casing are engaged pivots 34, so that the pivoted members may be moved to lie close against the outer face of the casing or with their free edges that project beyond the end of the casing in close relation to permit of free flow to the casing or to partially close the end of the casing, as may be desired. To shift these members of the, gate, a rack-bar 35 is slidably mounted on the casing, and connected to one end thereof are links 36 and 37,

which are pivoted to the bar and to the corresponding members of the gate. A vertical operating-shaft 38 is provided and has a pinion 39 at its lower end, which engages the rack-bar, so that when the shaft is rotated in one direction the bar will be shifted to open the casing and when rotated in the opposite direction the bar will be shifted to close the casing. A hand-wheel 39 is provided for this shaft.

It will be understood'that in practice modi fications of the specific construction shown may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. In amotor, the combination with a frame, and a casing horizontally disposed in the said frame, of means for regulating the flow of the motive fluid through the casing, said means consisting of a two-part gate having wings disposed upon the end of the casing and adapted to be opened and closed by means of a rackbar slidably mounted on the casing, links pivoted to the bar and to corresponding wings of the gate, a vertical shaft having a pinion at its lower end adapted to engage the rack-bar, and a hand-wheel mounted upon the upper end of the said vertical shaft to rotate it to thereby operate the rack-bar and therefore the gate.

2. The combination with a frame, a casing horizontally disposed in the said frame, means for raising the said casing, a motor within the casing, a shaft carrying a pulley-wheel mounted upon the casing, and sprocket-chains engaging the motor and the said shaft, of means for regulating the flow of motive fluid through the casing, said means consisting of a twopart gate having wings disposed upon the end of the casing and adapted to be opened and closed by means of a rack-bar slidably mounted on the casing, links pivoted to the bar and to corresponding wings of the gate, a vertical shaft having a pinion at its lower end adapted to engage the rack-bar, and a hand-wheel mounted upon the upper end of the said vertical shaft to rotate it to thereby operate the rack-bar and thereforethe gate.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN A. MAREK.
